Application ied April 13, 1922. Serial No. 552,286.

' 10J- exact `description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relatesto a machine for handling motors and particularly to a ma- 15..chin e adapted 4to supportan internal combustion motor for various operations. Such motors are often overhauled to place the same in first class condition and during such repairs, the bearings for the crank shaft are 2,0 usually relined and suoli bearings brought tov a. properly Vsurfaced condition. Other operations performed' at such times include valve .grinding and valve setting.

It' is an object of this invention to provide 25. a machine having a rotating means for receiving and turning the crank shaft of the motor and also, having an independently rotatable trame'for supporting and holdingr the frame of the motor. i 30. It is a further object of this invention to provide such a frame comprising a pluralityv Vof longitudinally andtransversely adjustable lmembers adapted to hold-various typesV and sizes 'of motors.

35. It is another object `otthe invention to provide eiiicient and convenient .means for turning the motor supporting freine and ior holding the same in .various degrees of roV tated movement. Y

`4:@ These and other objects and advantages of the invention will more fully appear from the following description Vmade` in connec4 tion with the accompanying :lrawings in which like reference characters refer .tothe .same prtsthroughout the different views, and in which, 1

Referring to the drawings, the machine comprises a suitable base member having longitudinally extending' members l and, transversely extending end members la.

F irmly secured to and rising from the baseV arel vertical members 2, these members converging toward their upper ends where they are formed as capped bearings having the cap members 2fL bolted thereto. Suitable bearings 3 are held in place between the members 2 and 2a, and a shaft 4 is journaled 70 in the adjacent bearings 3 at one end of the machine, as shown at the left on Fig. 1. This shaft is held in place at its outer endA by a collar attached thereto by a set screw and carries at its inner end a fork member be- `75. tween the arms of which is pivoted a supporting socket member 6, which socket, in turn, carries-therein a smaller socket member 621 pivoted thereto by pivot members 6b on an axis at right angles to the pivotal axis of member 6. The shaft 4 is provided with a belt pulley 7 formed as a clutch pulley of any usual or ordinary type having a movable clutch member adapted `to be moved by eitherl one of a pair of levers 8 locatedat 85 each side of the machine and secured to a shaft pivoted in suitable bearings projecting from the member 2, only one of said bearings and levers being shown. A suit;

in the sliding sleeve 9 mounted on the shaft V4 isV moved by the' levers 8 to engage or disengage thechitch member with the pulley 7 and tliusconnect and disconnect the shaft 4 In the bearing 3 at the Vother end 95 of the machine shown at the right in Fig. l,v

is mounted a longitudinally movable centerJ ing device l0 axially alined with shaft 4,

. termed as a handleat its outer end by which it is moved longitudinally of the machine. V:no

Mounted for rotation on the shaft fl between the member 5 and its adj acont: bearingr 3 is a sprocket Wheel or similar rotatable member 11 and mounted for rotation in the bearinn S about the member immediately inside or the bearing 23 is a similar sprocket. or rotating member 12. A shaft 13 is journaled for rotation in suitable bearingsA secured to the members 2 at one side of the machine which shatt is provided with sprocket pinioiis alined ivith the members 11 and 12 and chains 1er' connect said members and pinions. The sha'tt 13 is provided with a hand crank 15 at one end olI the traine and the said shaft is made of square section on its projecting end and adapted to be engaged by a swinging hook or pa\vl member 16 provided with a. notch therefor adapted to hold the shalt 18 against rotation. lith this structure it will be seen that by turning;` the crank 15, the Vmembers 11 and 12 will be rotated about the axis ot members l and 10 and independently of rotation of slia'lit l.

Bigidly secured to and extending at one side of the members 1l and 12 are reversely disposed members 17 having' horizontal pro jecting parts to which are rigidly bolted bars llentending at one side or and transe versely ot the asis ot members l and 10. Passingv through the Vslots in the bars 18ers the threaded Shanks extending atl right angles to and firmly secured to slotted bars 19, which bars extend longitudinally o'l the machine between the bais 18. The

bars 1S by suitable lock nuts disposed at each side ot said'bars. A pair ot' members 2O formed of flat bars have their ends bent to extend along' and contact the bars 19 and be connected thereto, said ends being apen tured and being connected to said bars by boltspassing through said apertures and the slots in bars 19 ivheieby the said members can Vbe moved along the bars 19 and lirmly "posite side to receive aber 22. the members 20, 21V and 22 being connectedln'. a single headed and nutted bolt extending; Vthrough .Y

the slots in members 29 and 22 and through v"an aperture formed in the member 2l. The

members 20ai'e thus connected' to 'torni a yoke 'from the central portion ot, which the member 22- extends toward the axis oit the members 4 and 1.0 and this member 22 is Lbentlaterally at its upper end and receives the'threaded Vends of a elevis oi' U-shaped clampinpinember 23, the ends of which are provided ivitlii suitable adjusting nuts.A

7A pan2ilris provided and sug'iported on .the basev member 1n for catching,- and holding said slianks are held in adjusted position in the the oil, grease and other refuse from the motor. A pan 25 is also secured in a bracket rising from the member 2 at'the right hand end ot' the machine, this latter pan forming a convenient holding means for nuts, screws, and other small parts ot the motor aswell as i'or tools. Y

1n operation, the motorA ot the automobile type Will usually be supported in theV machine as illustrated by ri in dotted lines in Fig. 1. T he shaft ot the motor Will'have one end disposed in the socket pivoted inside ot" socket 6 and the other end of the motor shaft will be supported and centered by the member l() engaging the end thereof, The frame on the motor will rest upon the bars 19 and will be clamped to said bars by having bolts passing` through Vthe attaching lugs oit the motor and tl'irougli the Aslotsin said bars. The end of the motor shaft held by member 10 may be additionally steadied and clamped in position by the member 22, thershait passing through the yoke 23 secured to t-he end thereof. The bars 19 can be transversely adjusted to suit the attaching lugs of the motor, by moving the projecting threaded ends thereof' in the bars 1S,v and by adjusting` the members 20. The memberV 22 can fbe suitably brought to the desired position by moving;- the same lengthwise in the member- 21. After the-motor has been secured to the siuliporting- Vtraine formed by the members 17, 1S and 19, various operations can. be

performed thereon. 1f it is desired to turn the motor to various positions, the paivl 16 will be released and the motor supportingl frame turned by turning the crank 15 which will, in turn, rot-ate the members 11 and 12 through thechains 14. lt will beV noted that the members l1 and 1.2 are much larger in diameter than the piniofns on sha'lt 13 and that said shaft can be held in; position at its quarterturn thereof by the'ipaivl 16. The motor A can, therefore, be held in a `large number of different Arotatable positions and in different degrees of rotative movement. llllien the motor earings have been suitaoly placed and finished, the mot r shatt can be rapidly turned by poiver applied VVto the pulley 7, therrotation being; controlled by the operation ofthe c uteh member for said pulley manipula-ted by levers '8: YThe motor shaft. canthus'be driven as Vlongrias Vdesired before the motor is taken outpot1 the machine Vand the said Vshatt Vand Vits.bea-rings broug'litf to the `proper bearingY condition-before the tain thefitthereof; For thispurpose a Yhand Wheel 26 .is provided on sbatte, ivhi n can be graspedfaiid,turned to thus turn 'the motor sh'a'lit.-r`he operator can usuallv'tell by the resistance to the turning;- of the shaft* or by the teelof the wheel 2G just h vv* theY motor shaft is run at; high speed to test ,out

"-the bearings, Theoperations on the motor can thus be entirely completed Without the necessity of re-inountingithe same in the automobile and then running the Vsame to bring-.the bearings to proper condition. lt will, of course, be apparent that many other operations can be Conveniently performed on the motor While the same is held and manipulated in the machine. "j i From the above description itis seen that applicant has provided a simple and elicient device for manipulating a motor during operations thereon. The parts of the inachine are comparatively feiv, quite rugged in construction and the machine can be made Without great expense.

It Will, of course, be junderstood that various changesmay ,be made in 'the form, details and arrangement of the parts Without departing from the scope of applicants invention which, generally stated. consists in the matter shown and described and se'" forth in the appended claims.V
